AGRICULTURAL MACHINE.

durable machine by the use of which seed may be plantedat the same time the ground is pulverized. The invention is illustrated in II the accompan ing' drawings and will be hereinafter ful y set forth. 1 Inthe drawings: I

Figure 1 is a plan view, partly broken away, of a machine embodying my invention; v Fig. 2 is a side elevation of the same, and

Fig. dis a rear elevation. T In carrying out my-invention, I employ a frame '1 which is rectangular in plan view and consists of cross bars and side bars rigidly secured; together. To the front cross bar of the frame is secured a draft pole or tongue 2,:1nd. depending from the main frame is a supplemental frame '3 which is of the same general form as the main frame.

At the sides of the supplemental frame, I

secure thereon'journal'boxes 4 in which are mounted axles'5 and-6, each of which carries a gang of rollers 7 having ridged or substantially conical circumferential surfaces,

the rollers of the two gangs being staggered relative to each other, as will be readily understood upon reference to Figs. 1 and 3. As the machine is drawn over the ground, the front gang of rollers will cut into the soil so as to produce furrows and the rear gang of rollers will ride upon and out through the ridges between the furrows produced by the front gang so that the surface will be left in a finely pulverized condition in which the seeds will quickly germinate. It will be readily understood also that, if seeds be deposited in the furrows or troughs formed by the front gang of rollers", the dirt turned aside'from the ridges bythe second gang of rollers will be'thro w n over the seeds so that they will be at once covered.

. Secured upon the main frame transversely thereof is a hopper or seed box 8 which may be of any well-known construction and from the bottom of which a plurality of 'seed Application filed April 21, 1923. Serial No. 633,686.

. spouts 9 depend between the front and rear rollers. Obviously the seed from the hopper will flow through these seed spouts and they are so arranged that each spout will be alined with the peak or'ridgeof a roller in the front gang and, consequently, the seed will be deposited in the furrows formed by said gang of rollers. A shaft 10 extends through the bottom of the hopper 8 so as to 435 agitate the seed therein and effect the feed ing of .the same through the seed cups and the spouts in the usual manner, and actw ate the said shaft a sprocket 11 is secured. upon one end of the same, a chain 12 being 79 trained around the said sprocket and a sprocket 13 on the axle v5 of the front rollers;

Disposed against the back wall of the hopper 8 and supported by the same and by the main frame is a supplemental hopper i l from which discharge spouts 15 eaten rear wardlyloverthe rear gang of rollers to de' liver seed onto the ground in rear of the same. This-hopper 14 is intended more particularly for carrying grass seeder other g0 small seed which is sown broadcast, and

through the bottom ofthe same is. extended an agitating shaft 16 equipped at one end. with a pinion 17 which is adapted to mesh with asimilar pinion 18 on the seed shaft 10. The pinion 17 will be mounted 'upon the shaft 16 in any manner which will permit its ready removal when it is desired to throw thesaid shaft out of or the pinion may be slidably mounted or other wise arranged so that the operation of the said shaft 16 may he controlled-at will.

I To the rear cross bar and to an intermedh ate cross bar of the frame 3. It secure a plurality of scrapers 19 which extend downat wardly and forwardly therefrom. to bear against the surfaces of the rollers in the respective gangs and scrape therefrom any dirt that may tend to cling thereto. Ti es-e scrapers may be conveniently secured in place by eye bolts, as shown at 20, and to the said eye bolts I attach the front ends of Spreaders or eveners 21 which consist of chains or loosely connected rings and are adapted to run free upon the ground in rear of the machine so that the spreading of the surface soil will be even and complete.

As the machine is drawn over the field, the action of the rollers upon the soil will thoroughly cut up and pulvc'riae the same and 1 0 at, the same time press the surface soil so that it will be very firm and will hold any m seed deposited therein being blown away. The machine is compact, stso and durable and by itsilse seed will ed in snows immediately after i so formed and will then be at s so with a fine mulch so that ination will be. rapid and very few :iiiur s in germinate will develop The Helms may be utiiized to plant any desired 3 O1 to plans grass seed for lawns oi: as may be preferred, and it may bio aiso by the use of the machine to uitemsousiy plant anci other seeds vhich the grass is not a risiriment.

thus described the invention what ned as new is: An agricultural machine comprising a main frame, inciuding side bars and cross A that may be in the ground and also bars firmly Connected; a iair of depending supports rigidly fixed to each of said. side bars, and a su'pplemental frame having sio bars and Ya rear cross to said depending supports, front and. rear journal boxes on the side bars of saidsupplemental frame, 'axles mounted in said journal boxes each-of said axles being providsd. with a gang of rollers having ridged eir cumferentiai surfaces and spreader. chains attached to the rear, bar OfSfiQid SUPPlQIYIQiliLfll frame, seed dispensingmem s mounteo upon said=maingframe provided with spouts delivering behind the respective gang's of rollers and in alinement Withihfi respeetive ridges thereof,- andvmeans for actuating seici seed dispensing means, y

In testimony whereof I afix myv 5i atm'e.
